Patent DE-3545333-A1 (DE)
Inventor: HARTMANN ERNST-SIEGFRIED
IPC: F02F1/38
Filed: 1985-12-20
Abstract: An air-cooled block cylinder head adapted for mounting on an open-deck cylinder casing of an internal combustion engine. In order to maintain a tight seal of the cylinder head to the cylinder casing, the combustion chamber floor of the cylinder head is designed to be deflected in a manner that does not adversely affect the sealing of the cylinder head to the cylinder casing. This is achieved by designing the cooling chamber side of the cylinder head floor with a gradually changing floor wall thickness in the area directly above the cylinder combustion chamber. In the preferred designs, the combustion chamber floor is designed to be concave or convex. The cylinder head also includes features for effectively cooling the combustion chamber floor and for isolating the exhaust conduit.

Abstract: A method for the production of a groove milling cutter for wood, plastic and similar materials from a rotationally symmetrical base body into which flutes are milled or ground from the front end of the milled part to be formed from the base body, parallel to the longitudinal axis thereof. The cutting edges (11A, 11B) are formed by grinding a first flute (3A) into the base body (1) in a first operation using a grinding wheel (2) at a curved section (8) of the grinding wheel. The base body is turned by an angular amount, and in a second operation a first cutting edge (11A) is sharpened by grinding the back at a section (10) of the grinding wheel. Subsequently, the base body (1) is turned by a further angular amount and the next flute (3B) is ground in in a third operation. In a following operation, the next cutting edge is sharpened. The aforementioned operations are carried out successively until all the flutes (3A, 3B) are formed and all the cutting edges (11A, 11B) are sharpened. <IMAGE>

IPC: A01K97/04
Filed: 1987-03-31
Abstract: In the case of a device for fishing, with a fishing rod, a fishing line guided thereon, and a bite monitor, readily responding bite monitoring is achieved, even with cautious fish, in that the bite monitor has two or more telescoping elements, of which the bottom one can be fixed in the ground and the top one has, at its free end, a guide for the fishing line, it being possible to draw the telescoping elements out of a retracted starting position by pulling on the fishing line.

Patent DE-3710930-A1 (DE)
Title: Eccentric spiral pump
Inventor: GRUBER HEINZ
IPC: F04C15/00
Filed: 1987-04-01
Abstract: The rotor (3), which is received eccentrically rotatably in a stator, of conventional eccentric spiral pumps used for conveying mortar represents a costly component which is exposed to great wear in particular on the pressure side and which is usually discarded after wear occurs on one side. The aim of the invention consists in guaranteeing better utilisation of the rotor (3) and in this manner contributing to increasing the life of the functional unit consisting of stator and rotor (3). In an eccentric spiral pump according to the invention, both face-side ends of the rotor (3) are provided with square profiles, the external dimensions of which are dimensioned smaller than the core diameter of the rotor (3). The possibility thus exists, in the event of wear of the rotor (3) occurring on one side, of inserting the same into the stator in the opposite direction so that the region which is not yet worn now passes into the high-wear pressure-side part of the stator. A contribution is thus made to a more complete utilisation of the rotor (3), in particular in the case of such eccentric spiral pumps, by means of which a great delivery height is to be overcome or which, for other reasons, have to apply a great output pressure. <IMAGE>

Title: Method for determining the time constants of elements such as sensors, measurement value pickups and the like, and device for carrying out the method
Inventor: TANK VOLKER DIPL ING
IPC: G01R27/28
Filed: 1987-04-23
Abstract: A method for determining the time constants of elements such as sensors, measurement value pickups, measurement value transducers, transmission elements, actuators, controllers, electrical filters and the like is created. In this method, the step response of an element is experimentally generated in the form of an electrical voltage and then converted into a number n of digital measurement values. From these measurement values, the time constants of the respective element and the excitation amplitude at the element input are then determined by using the mathematical expression for this step response by using compensating iteration algorithms, in such a manner that the theoretic step response belonging to the time constants to be determined and to the excitation amplitude corresponds to the measurement values as accurately as possible. The time constants thus found are then determined as the true time constants and the excitation amplitude thus found is determined as the true excitation amplitude. Using the method according to the invention, the determination of these time constants can be carried out simultaneously in only a single measuring cycle with greater accuracy, fewer processing steps and thus altogether faster than previously even in higher-order elements, that is to say in elements having several time constants.

Title: Muffle moulder
Inventor: KESEL ERWIN
IPC: A61C13/20
Filed: 1987-05-12
Abstract: In the manufacture in particular of dental casting models, corresponding quantities of embedding compound are required. Although the quantity of embedding compound used in each case is in itself not very great, the overall requirement per year in the dental laboratories equipped for this purpose adds up to quite considerable quantities. The novel muffle moulder which is to be provided is intended to help reduce the quantities of embedding compound needed. In order to reduce the quantity of embedding compound needed, a muffle insert (5) is provided, which can be designed in one piece with the muffle ring (3) or as a separate component. By means of this muffle insert (5), which at the same time is provided on one side with a casting recess (7), casting models can be manufactured with low quantities of embedding compound. The muffle moulder is especially suitable for casting techniques, in particular in the area of dental technology. <IMAGE>

Title: Process for isolating H2 and CO

IPC: C01B32/40
Filed: 1987-12-10
Abstract: Synthesis gases having a low methane content, such as those from partial oxidation, can normally not be separated into the components by means of methane scrubbing. A process for isolating H2 and CO from a synthesis gas containing these materials and small amounts of CH4 by means of scrubbing with liquid CH4 is possible when a CH4-containing gas is mixed into the liquid-phase fraction, containing CH4 and CO, of the methane scrubber prior to the rectifying separation thereof into a CO top fraction and a CH4 liquid-phase fraction (bottom fraction) which serves, at least in part, to replenish the scrubbing agent of the methane scrub.

Title: Semiconducting gas sensor
Inventor: ZIMMER GUENTER PROF DR
IPC: G01N27/414
Filed: 1988-03-08
Abstract: A gas sensor is described which is constructed from an electrode-insulator semiconductor structure with a gate electrode which can be directly or indirectly heated. In a preferred embodiment, the gas sensor consists of a MOSFET transistor whose gate electrode is designed as a heatable resistor which covers a trench-shaped insulating layer in a bridge shape and forms with it a hollow space. By so doing, the gas-sensitive layer is free between the gate electrode and the oxide layer and is accessible for the measurement of different gases. By means of the heatable electrode, heating of the whole MOSFET transistor is avoided, by which means its lifetime and the 0-point drift are reduced.

Title: Apparatus for utilising the kinetic energy of sea waves
Inventor: BRUECK ROLF DR
IPC: F03B13/18
Filed: 1988-04-16
Abstract: The invention relates to an apparatus for utilising sea waves with the aid of a floating body, a connection element to the sea bed and an energy converter. Apparatuses which exploit in particular the up-and-down motion of the waves are known. Both the high building costs for inert base systems and the poor efficiency are disadvantageous. The object of the invention is to find a simple construction having a high efficiency, which can adapt itself reliably to changing sea conditions. This object is achieved in that the floating body is constructed as a converting element which preferably converts the horizontal components of the wave forces into horizontal movements which are transmitted to a hydraulic pump which is inserted in the connection element and is connected on the high-pressure side, via an outlet valve, to a reservoir. <IMAGE>
